Best Google Chrome Ad-block extensions

These are the best adblockers for Chrome

  1. AdLock
  2. uBlock Origin
  3. Adblock Plus
  4. Ghostery
  5. AdGuard

In a world where online advertisements are viewed as a necessary evil to keep websites free to access, ad-blockers are becoming more and more popular. Unfortunately, many websites business models abuse this, with intrusive pop-up ads, trackers within cookies, and scammers running riot. Luckily by using an ad-blocker, Chrome users can avoid annoying ads and stop nosy advertising companies tracking what they do online!


The best ad-blocker extensions for Chrome

Our experts have reviewed almost every Google chrome ad-block extension out there and, in our opinion, these six services are the best currently on offer. All the options listed below (except AdLock) have free tiers and will provide an excellent defense against intrusive ads and website tracking.

AdLock is a lightweight, highly effective system-level adblocker, capable of protecting not just browsers but all manner of apps as well.

  • Pricing

    • 60 months: $1.51/mth
      57% OFF
    • 12 months: $2.94/mth
      17% OFF
    • 1 month: $3.5/mth
  • Pros

    • Cheap subscription options
    • 24/7 support
    • Blocks ads in multiple apps at the same time
    • Support for multiple platforms and 5 devices per sub
  • Cons

    • Requires manual installation on Android
    • No free version

Rather than running as a browser extension, AdLock is a stand-alone app that runs on your device of choice, with support for five different devices on one subscription and apps available for Mac, iOS, Android (though not through the Play Store, the .APK must be manually installed on your device) and Windows PCs. It will protect not only Chrome, but all your other apps and browsers as well. It can even block YouTube ads!

Reasonably priced

Unlike some of the other options on this list, AdLock does not have a free tier. Even so, we think it's well worth your money, with competitively priced monthly, yearly or five-yearly subscription options on offer. We think it's a brilliant choice for both mobile and desktop users and should you find it's not quite a fit for you, it's backed up by a 30-day money-back guarantee so you can try it out with no risk at all.

Responsive support

One of the benefits of opting for a paid product rather than a free one is that you get proper customer support. In our testing, we found AdLock's support super responsive to our questions, updating their filters in a matter of hours when we flagged sites that weren't working properly. You won't get that sort of fast-reply with any of the free options on this list.

Block apps entirely

Not only capable of blocking ads, AdLock comes with built-in firewall functionality to restrict internet connectivity for apps and browsers. This is especially important if you're using mobile broadband as they often have fairly stingy download caps where every megabyte counts. With AdLock, you can restrict internet connections to just browsers, messengers, or only to selected apps. This way, you can make sure nothing is quietly downloading some massive update in the background that's going to use up your allowance.

uBlock Origin is a free, Open-source privacy extension for Chrome, focusing on blocking ads, trackers, malware and other privacy threats.

  • Free option

  • Pros

    • Totally free!
    • Open source and lightweight
    • Over 10 million active users
    • Extensions for all popular browers
    • Jam-packed with filter lists
  • Cons

    • Not available for iOS

uBlock Origin is a fork from the original uBlock ad blocker. It's completely free, like most of the other extensions on this list, and is completely open-source. It maintains unparalleled transparency, which sets it apart from many competing products, featuring a statistical breakdown of how well the ad blocker has performed across the current session.

Lightweight ad-blocking

Top-of-the-range filter lists are used to block intrusive advertisements, malware, and trackers, including AdServer List, Advanced Tracking List, EasyPrivacy List and Malware Domains. uBlock Origin also allows users to choose separately whether they block pop-ups, large media elements, cosmetic filtering, remote custom website fonts, JavaScript and more, all while remaining lightweight, minimally impacting how your device runs. With efficiency as the main priority, uBlock Origin is ideal for a relatively resource-hungry browser such as Chrome as it taxes your system much less than other competition with a low resource overhead.

Simple setup

uBlock Origin can be downloaded from your add-on/extension page of choice within your browser. There's support for Firefox, Chrome, Opera and Microsoft Edge and, unlike some of its competitors, uBlock Origin works right out of the box. With a one-click install you'll be set up and protected from adverts and trackers, whereas some of uBlock's competitors still leave these things enabled and rely on you to go in and manually disable them which can be a daunting prospect for inexperienced users.

Additional privacy

uBlock is what's described as a "wide-spectrum content blocker". What this means is that it's more than just an ad-blocker, it's a general purpose blocker for all kinds of internet irritations. As well as blocking ads, it blocks trackers, it can disable pre-fetching to keep you from leaking your IP address to pages you haven't yet loaded, and it can even help protect you from WebRTC leaks!

Adblock Plus is one of the original ad-blocking solutions. It's free, and available for multiple browsers

  • Free option

  • Pros

    • Can be used for free
    • Open source
    • Over 10 million downloads
    • 52 languages supported
    • Users can create personalized whitelists
  • Cons

    • Part of the Acceptable Ads program
    • Some ads can still sneak by

Adblock Plus first made a name for itself on Firefox before being ported over to Chrome. Its open-source approach has prompted several notable competitors, with the similarly named but unaffiliated 'AdBlock' using Adblock Plus' source code. The organization behind it is responsible for establishing one of the most comprehensive filter lists out there, as well as adding support for 52 different languages. The Adblock Plus extension also sits among the most frequently updated.

Simple to use

It doesn't matter how good your product is if it's too difficult to use, and Adblock Plus makes sure that getting started is a breeze. Just install the extension and you're good to go, though you will need to go into the settings if you want to change the Acceptable Ads filter or start whitelisting individual sites. AdblockPlus even shows you how many ads it's blocking on the page, so you can immediately see how effective it's being at streamlining your browsing experience.

Blocks ads and more

It wouldn't be much of an ad-blocker if it didn't block adverts, and Adblock Plus certainly doesn't disappoint. While the inclusion of the Acceptable Ads scheme may be controversial for some users, Adblock Plus is still perfectly capable of blocking YouTube adverts, pop-ups, pop-unders, multimedia ads, banner ads and more. All this not only saves you bandwidth, it will improve website loading times and even protect you from adverts carrying malware.

Selective ad blocking

As you may already know, some websites depend on their advertising to survive, and maybe there are some sites you visit regularly, and you want to support them by leaving adverts enabled on their pages. Adblock Plus allows you to configure whitelists where sites are allowed to show their ads, especially if they are non-intrusive and do not really disturb your browsing session. This is above and beyond Adblock Plus' built in Acceptable Ads filter, which can also be turned off if you disagree with them about what adverts are acceptable!

Ghostery is a powerful Open-source privacy tool for Chrome users. It blocks ads, trackers and more with a paid tier for more functionality.

  • Free option

  • Pros

    • Free to use
    • Sleek UI
    • Detailed tracker statistics
    • Blocks adverts and trackers
  • Cons

    • Blocklist customization can be complicated
    • Collects user data unless you specifically opt out

Ghostery is built with privacy in mind, designed to stop trackers and block advertisements. The extension blocks ads, site analytics, and adult advertising trackers by default, but this can be customized depending on your needs. Unblocked and unknown trackers are also anonymized with enhanced anti-tracking turned on.

Tracker blocker

Ghostery can block an impressive number of different web trackers, including ad trackers, analytics, social media, comments, chat and more. You can even choose whether to restrict or trust sites on a case-by-case basis. It even tells how you many trackers are on the site you're visiting, displaying a handy little floating box that displays the number of trackers it's found, giving you access to see exactly what's on the site and which are allowed/blocked.


Smart-Browsing is a clever little feature Ghostery employs when full-on ad/tracker blocking would stop a site from working properly. Instead of completely blocking the tracker, Ghostery lets it run, but removes any of your personal information from it. Not only does this ensure that your sites still work properly while protecting your privacy, it also means that any trackers using browser fingerprinting will be useless. Ghostery modifies the information that's sent back, which means that your fingerprint will keep changing so you can't be tracked.

Ad blocking

All this is fine and good, but the main purpose of an ad-blocker is to, well, block adverts. Ghostery doesn't disappoint in that regard, being more than capable of blocking banners, pop-ups and interstitial adverts to ensure that your web browsing experience will be a smoother, cleaner and faster one. The best part of all this is that the browser extension is available for the low price of absolutely nothing. It's entirely free to download and use, so there's no reason not to give it a try for yourself.

AdGuard is an impressively flexible and customizable ad-block extension that can block intrusive ads, website trackers, cookies and more.

  • Free option



    • Free extensions: $0/mth
    • 1 yr personal license/3 devices: $29.88/mth
    • lifetime personal license/3 devices: $59.99/mth
    • 1 yr family license/9 devices: $65.88/mth
    • lifetime family license/9 devices: $129.99/mth
  • Pros

    • Free to use
    • Open source
    • Works with Youtube adverts
    • Stand-alone version available
  • Cons

    • Range of customization can be overwhelming
    • Extension sometimes freezes

AdGuard's user base may not be as impressive as of uBlock Origin's or Adblock Plus', its ad-blocking credentials are nothing to be sneezed at. AdGuard's Tracking Protection filter is designed to remove all forms of tracking with a filter list even larger than Ghostery. Version 4 of the extension has just been released and brings with it an impressive suite of new features and quality of life updates that make it well worth a look.

Stand-alone and browser

AdGuard comes in a variety of flavors depending on your needs. There's both a stand-alone desktop version available for MacOS, Windows and more, and also a browser extension that can be downloaded and used on your browser of choice - like Chrome! While there is a paid offering available that offers additional functionality, the browser extension can be used free of charge.

Stealth mode

One of the greatest feathers in AdGuard's cap is Stealth mode, which offers a truly impressive array of options for blocking not just adverts and trackers but a range of other online options that can compromise your security. You can hide your search queries so websites don't know what you typed in to find them, block WebRTC entirely to protect your IP address, hide referrer details, block or limit cookies and more besides. This flexibility makes AdGuard one of the most full-featured Chrome extensions around.

Blocking adverts

Again, all of this is great, but it's useless if an ad blocker doesn't block adverts. AdGuard won't let you down, with the ability to set up and customized multiple filters for all kinds of ads and trackers. It comes with categories already set for ad-blocking filters, social media-related filters and more. You can either just the individual filters you want, or all of them at once. All of this functionality comes free in the browser extension, and the stand-alone version comes with a 60 day money-back guarantee, so there's no risk in giving the paid version a try!

Why do I need an ad-blocker?

Every website provides a different experience, but most have one thing in common: they are all trying to build a personal profile of your interests by tracking your data or doing their best to coerce clicks on advertisements. These ads are sometimes intrusive and can be taxing to your system when trying to load them. Other times, they are deceptive and are used to distribute data-stealing malware. Some websites even use crypto-jacking code to mine cryptocurrency in the background, at the expense of your hardware and electricity.

How will an ad-blocker protect your browsing?

The ad-blockers on this list are designed with privacy and security in mind, helping to preserve your anonymity online and keep you safe from both malicious or just downright annoying code and adverts. A wide selection of filter lists helps to identify trackers, block advertisements and blacklist hundreds of thousands of known online scams. It’s important to choose your ad-blocker carefully, as their accessibility has prompted many copycats and scammers to fill app stores with fakes that look almost identical to the real things. If our list doesn’t do the trick for you, looking at reviews and seeing just how many people have installed an extension can help settle your suspicions.

Alternatives to Extensions

Browser extensions are a great place to start with ad-blocking, security and privacy, but they are limited in their abilities. You need to download an extension for every browser you have, and they only work within that specific browser. That isn't necessarily a bad thing, but it means any other apps you use outside of the browser will still serve you with adverts.

Instead, you could take a look at the alternative ways of ad-blocking when surfing the web, such as stand-alone applications, VPNs with extra features or router-loaded ad blockers.
